PIC32MX250F128C-I/SO

32-bit Microcontrollers (up to 128 KB Flash and 32 KB SRAM) with Audio and Graphics Interfaces, USB, and Advanced Analog

Microchip Technology 

PIC32MX1XX/2XX

REGISTER 19-2: PMMODE: PARALLEL PORT MODE REGISTER (CONTINUED)

bit 5-2 WAITM<3:0>: Data Read/Write Strobe Wait States bits(1)

1111 = Wait of 16 TPB

•

•

•

0001 = Wait of 2 TPB

0000 = Wait of 1 TPB (default)

bit 1-0 WAITE<1:0>: Data Hold After Read/Write Strobe Wait States bits(1)

11 = Wait of 4 TPB

10 = Wait of 3 TPB

01 = Wait of 2 TPB

00 = Wait of 1 TPB (default)

For Read operations:

11 = Wait of 3 TPB

10 = Wait of 2 TPB

01 = Wait of 1 TPB

00 = Wait of 0 TPB (default)

Note 1: Whenever WAITM<3:0> = 0000, WAITB and WAITE bits are ignored and forced to 1 TPBCLK cycle for a

write operation; WAITB = 1 TPBCLK cycle, WAITE = 0 TPBCLK cycles for a read operation.

2: Address bit A14 is not subject to auto-increment/decrement if configured as Chip Select CS1.
