CHITXPTRB3

CHITXPTRB3 bits (Initial value: 00000, W)

These bits represent the TDM switch pointer which defines the transmit channel

timeslot for byte 3 of the CHI transmit holding register B; register B handles all

timeslots from channel (CHINCHAN

+ 1) to channel (CHINCHAN × 2 + 1). The

value loaded for this TDM switch pointer is the desired timeslot number minus

(CHINCHAN

+ 1).

These bits represent the TDM switch pointer which defines the transmit channel

timeslot for byte 2 of the CHI transmit holding register B; register B handles all

timeslots from channel (CHINCHAN

+ 1) to channel (CHINCHAN × 2 + 1). The

value loaded for this TDM switch pointer is the desired timeslot number minus

CHITXPTRB0

CHITXPTRB0 bits (Initial value: 00000, W)

These bits represent the TDM switch pointer which defines the transmit channel

timeslot for byte 0 of the CHI transmit holding register B; register B handles all

timeslots from channel (CHINCHAN

+ 1) to channel (CHINCHAN × 2 + 1). The

value loaded for this TDM switch pointer is the desired timeslot number minus

(CHINCHAN
