11.6.2.2 Channel Function Select Registers
11.6.2.3 Host Sequence Registers
11-16
MOTOROLA
bit is set and the CIRL field has a non-zero value. To clear a status flag, read CISR,
then write a zero to the appropriate bit. CISR is the only TPU register that can be ac-
cessed on a byte basis.
Encoded 4-bit fields within the channel function select registers specify one of 16 time
functions to be executed on the corresponding channel. Encodings for predefined
functions in the TPU ROM are found in Table 11-3.
The host sequence field selects the mode of operation for the time function selected
on a given channel. The meaning of the host sequence bits depends on the time func-
tion specified. Refer to Table 11-4, which is a summary of the host sequence and host
service request bits for each time function. Refer to the TPU Reference Manual
(TPURM/AD) and the Motorola TPU Literature Package (TPULITPAK/D) for more
information.
