Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
bit 6-5
bit 4-3
bit 2
bit 1-0
BUSY: Busy bit (Master mode only)
1 = Port is busy
0 = Port is not busy
IRQM1:IRQM0: Interrupt Request Mode bits
11 = Interrupt 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 generated, processor stall activated
01 = Interrupt generated at the end of the read/write cycle
00 = No interrupt generated
INCM1:INCM0: Increment Mode bits
11 = PSP read and write buffers auto-increment (Legacy PSP mode only)
10 = Decrement ADDR<15,13:0> by 1 every read/write cycle
01 = Increment ADDR<15,13:0> by 1 every read/write cycle
00 = No increment or decrement of address
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
MODE1:MODE0: Parallel Port Mode Select bits
11 = Master mode 1 (PMCSx, PMRD/PMWR, PMENB, PMBE, PMA<x:0> and PMD<7:0>)
10 = Master mode 2 (PMCSx, PMRD, PMWR, PMBE, PMA<x:0> and PMD<7:0>)
01 = Enhanced PSP, control signals (PMRD, PMWR, PMCS, PMD<7:0> and PMA<1:0>)
00 = Legacy Parallel Slave Port, control signals (PMRD, PMWR, PMCS and PMD<7:0>)
