Description
Default R/W
Prescaler Field for Watchdog Timer.
00 – Divide by 1
01 – Divide by 16
10 – Divide by 256
11 – Divide by 8192
00 R/W
Count Field for Watchdog Timer. Settings of 00 to 3Fh correspond to values between 1 and 1Fh R/W
64 times the prescale value. The period starts at the end of the command width period and
continues as long as PCM_WAIT_L is low. If terminal count is reached, an interrupt can be
generated.
Prescaler Field for Command Strobe Width.
00 – Divide by 1
01 – Divide by 16
10 – Divide by 256
11 – Divide by 8192
00 R/W
Count Field for Command Strobe Width. This field has values between 1 and 64. The com- 00h R/W
mand width equals:
tCMD = tPCLK × ([Prescale × Count] + 2)

Description
Default R/W
Prescaler Field for Address and Data Hold Time.
00 – Divide by 1
01 – Divide by 16
10 – Divide by 256
11 – Divide by 8192
00 R/W
Count Field for Hold Period. Settings of 00 to 3Fh correspond to 1 to 64 times the prescale 00h R/W
value. The period starts at the end of the command strobe. The hold time equals:
tHold = tPCLK × ([Prescale × Count] + 1) + constant
Prescaler Field for Address and Data Setup Time.
00 – Divide by 1
01 – Divide by 16
10 – Divide by 256
11 – Divide by 8192
00 R/W
Count Field for Address and Data Setup Time. Settings of 00 to 3Fh correspond to 1 to 64 00h R/W
times the prescale value. The period starts at valid address and ends when command strobe
is active. The setup time equals:
tSetup = tPCLK ×([Prescale × Count] + 1) − constant
