/* * MPC8xx Communication Processor Module. * Copyright (c) 1997 Dan Malek (dmalek@jlc.net) * * This file contains structures and information for the communication * processor channels. Some CPM control and status is available * throught the MPC8xx internal memory map. See immap.h for details. * This file only contains what I need for the moment, not the total * CPM capabilities. I (or someone else) will add definitions as they * are needed. -- Dan * * On the MBX board, EPPC-Bug loads CPM microcode into the first 512 * bytes of the DP RAM and relocates the I2C parameter area to the * IDMA1 space.

There are nearly 32 interrupts generated by CPM * channels or devices. All of these are presented to the PPC core * as a single interrupt. The CPM interrupt handler dispatches its * own handlers, in a similar fashion to the PPC core handler. We * use the table as defined in the manuals (i.e. no special high * priority and SCC1 == SCCa, etc...). */ #define CPMVEC_NR 32 #define CPMVEC_PIO_PC15 ((ushort)0x1f) #define CPMVEC_SCC1 ((ushort)0x1e) #define CPMVEC_SCC2 ((ushort)0x1d) #define CPMVEC_SCC3 ((ushort)0x1c) #define CPMVEC_SCC4 ((ushort)0x1b) #define CPMVEC_PIO_PC14 ((ushort)0x1a) #define CPMVEC_TIMER1 ((ushort)0x19) #define CPMVEC_PIO_PC13 ((ushort)0x18) #define CPMVEC_PIO_PC12 ((ushort)0x17) #define CPMVEC_SDMA_CB_ERR ((ushort)0x16) #define CPMVEC_IDMA1 ((ushort)0x15) #define CPMVEC_IDMA2 ((ushort)0x14) #define CPMVEC_TIMER2 ((ushort)0x12) #define CPMVEC_RISCTIMER ((ushort)0x11) #define CPMVEC_I2C ((ushort)0x10) #define CPMVEC_PIO_PC11 ((ushort)0x0f) #define CPMVEC_PIO_PC10 ((ushort)0x0e) #define CPMVEC_TIMER3 ((ushort)0x0c) #define CPMVEC_PIO_PC9 ((ushort)0x0b) #define CPMVEC_PIO_PC8 ((ushort)0x0a) #define CPMVEC_PIO_PC7 ((ushort)0x09) #define CPMVEC_TIMER4 ((ushort)0x07) #define CPMVEC_PIO_PC6 ((ushort)0x06) #define CPMVEC_SPI ((ushort)0x05) #define CPMVEC_SMC1 ((ushort)0x04) #define CPMVEC_SMC2 ((ushort)0x03) #define CPMVEC_PIO_PC5 ((ushort)0x02) #define CPMVEC_PIO_PC4 ((ushort)0x01) #define CPMVEC_ERROR ((ushort)0x00) /* CPM interrupt configuration vector. */ #define CICR_SCD_SCC4 ((uint)0x00c00000) /* SCC4 @ SCCd */ #define CICR_SCC_SCC3 ((uint)0x00200000) /* SCC3 @ SCCc */ #define CICR_SCB_SCC2 ((uint)0x00040000) /* SCC2 @ SCCb */ #define CICR_SCA_SCC1 ((uint)0x00000000) /* SCC1 @ SCCa */ #define CICR_IRL_MASK ((uint)0x0000e000) /* Core interrupt */ #define CICR_HP_MASK ((uint)0x00001f00) /* Hi-pri int. */ #define CICR_IEN ((uint)0x00000080) /* Int. enable */ #define CICR_SPS ((uint)0x00000001) /* SCC Spread */ #define IMAP_ADDR (get_immrbase()) #define CPM_PIN_INPUT 0 #define CPM_PIN_OUTPUT 1 #define CPM_PIN_PRIMARY 0 #define CPM_PIN_SECONDARY 2 #define CPM_PIN_GPIO 4 #define CPM_PIN_OPENDRAIN 8 enum cpm_port { CPM_PORTA, CPM_PORTB, CPM_PORTC, CPM_PORTD, CPM_PORTE, }; void cpm1_set_pin(enum cpm_port port, int pin, int flags); enum cpm_clk_dir { CPM_CLK_RX, CPM_CLK_TX, CPM_CLK_RTX }; enum cpm_clk_target { CPM_CLK_SCC1, CPM_CLK_SCC2, CPM_CLK_SCC3, CPM_CLK_SCC4, CPM_CLK_SMC1, CPM_CLK_SMC2, }; enum cpm_clk { CPM_BRG1, /* Baud Rate Generator 1 */ CPM_BRG2, /* Baud Rate Generator 2 */ CPM_BRG3, /* Baud Rate Generator 3 */ CPM_BRG4, /* Baud Rate Generator 4 */ CPM_CLK1, /* Clock 1 */ CPM_CLK2, /* Clock 2 */ CPM_CLK3, /* Clock 3 */ CPM_CLK4, /* Clock 4 */ CPM_CLK5, /* Clock 5 */ CPM_CLK6, /* Clock 6 */ CPM_CLK7, /* Clock 7 */ CPM_CLK8, /* Clock 8 */ }; int cpm1_clk_setup(enum cpm_clk_target target, int clock, int mode); #endif /* __CPM1__ */
