Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as 0
-n = Value at POR 1 = Bit is set 0 = Bit is cleared x = Bit is unknown
bit 15 BUSY: Busy bit (Master mode only)
1 = Port is busy (not useful when the processor stall is active)
0 = Port is not busy
bit 14-13 IRQM<1:0>: Interrupt Request Mode bits
11 = Interrupt is generated when Read Buffer 3 is read or Write Buffer 3 is written (Buffered PSP mode)
or on a read or write operation when PMA<1:0> = 11 (Addressable PSP mode only)
10 = No interrupt is generated, processor stall is activated
01 = Interrupt is generated at the end of the read/write cycle
00 = No interrupt is generated
bit 12-11 INCM<1:0>: Increment Mode bits
11 = PSP read and write buffers auto-increment (Legacy PSP mode only)
10 = Decrements ADDR<10:0> by 1 every read/write cycle
01 = Increments ADDR<10:0> by 1 every read/write cycle
00 = No increment or decrement of address
bit 10 MODE16: 8/16-Bit Mode bit
1 = 16-Bit Mode: Data register is 16 bits, a read or write to the Data register invokes two 8-bit transfers
0 = 8-Bit Mode: Data register is 8 bits, a read or write to the Data register invokes one 8-bit transfer
bit 9-8 MODE<1:0>: Parallel Port Mode Select bits
11 = Master Mode 1 (PMCS1, PMRD/PMWR
, PMENB, PMBE, PMA<x:0> and PMD<7:0>)
10 = Master Mode 2 (PMCS1, PMRD, PMWR, PMBE, PMA<x:0> and PMD<7:0>)
01 = Enhanced PSP, control signals (PMRD, PMWR, PMCS1, PMD<7:0> and PMA<1:0>)
00 = Legacy Parallel Slave Port, control signals (PMRD
, PMWR, PMCS1 and PMD<7:0>)
bit 7-6 WAITB<1:0>: Data Setup to Read/Write Wait State Configuration bits
(1)
11 = Data wait of 4 T CY; multiplexed address phase of 4 T CY
10 = Data wait of 3 T CY; multiplexed address phase of 3 T CY
01 = Data wait of 2 T CY; multiplexed address phase of 2 T CY
00 = Data wait of 1 T CY; multiplexed address phase of 1 T CY
bit 5-2 WAITM<3:0>: Read to Byte Enable Strobe Wait State Configuration bits
1111 = Wait of additional 15 T
CY
...
0001 = Wait of additional 1 T
CY
0000 = No additional wait cycles (operation forced into one T CY)
bit 1-0 WAITE<1:0>: Data Hold After Strobe Wait State Configuration bits
(1)
11 = Wait of 4 T CY
10 = Wait of 3 T CY
01 = Wait of 2 T CY
00 = Wait of 1 T CY
Note 1: WAITBx and WAITEx bits are ignored whenever WAITM<3:0> = 0000.
